IMPROVEMENT IN WELL- AND cIsIEsN EILTEES.

sPEc:c:EExsaeuIfIcJ:|511 T0 ALL WHOM IT MAY CONCERN:

B'e it known that I, WILLIAM I-I. WILEY, of Fredonia, in the county ofChatauqua, and State ,of-New York, u

have. invented a certain new and improved Well and Cistern Filterg and Ido hereby declarethat the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, making partof .this

specification, in which- Figure 1 is a central vertical section of myimprovements, represented in the bottomofa well. Figure 2 is ahorizontal section of the same in plane of line a az.

the filter.

Like letters designate corresponding parts in all the figures.

The object of my improvement is to provide a filter that may be attachedto the tube of a well orcistern, and then let down 'into thesame,whereby the water is subject to a thorough ltration before it is pumpedup for use; and the invention consists in the manner of constructing thefilter, ashereafter described, by which it is specially adapted to theuse and purpose above stated.

In the drawings, A represents the bottom portion of a well, with myimproved lter therein; B,`(g. 1,) .is a section cf an iron well tube,coupled to the filter-tubeC, in any ordinary manner as shown;` E, thebase-plate, xedly connected with the central tube C, to form thefoundation and bottom of the ilter; F, G, the outer and inner sides ofthe iilterin g chamber, formed of porousm aterial, or partly perforatedcases, secured as represented, or in any other suitable way, and D theupperfdisk or plate covering the filter. These disks are solid with theexception `of a hole in the upper one, D, for the passage of the tube C.The lowerbase-plate E and the tube C are preferably cast in a singlepiece, but may be rigidly connected together. by bolts or other means;the latter being provided with apertures or perforations, it', in itssides, of anydesired form for the iniiux of the water, and with both aninternal and external thread at its upper end for coupling with tubeB,-and for the purpose presently to be explained. The upper or coverplate, D, is made to fit ove'r the end of tube C,and rest upon the endsor top 4of the'cases and G, where it is firmly secured in place by thenut j, which screws on the end of the tube C, as shown in fig. 1. Thesides may be of any porous'material, as baked earthen, brick, 31' otherporous substance, or of the metallic cases F, G, which are provided withfine perforations, at and n', on one side of each and on opposite sidesof the filter, so that the water as it enters the perforated side ofthe' outer case, cannot pass directly and readily through the packing,L, and inner case into the water chamber, I, but is compelled topercolate around between the two cases through the filtering material,L, (which may he of any'suitable kndltill it reachesthe perforations, n,n', in the inner case G, as shown by arrows most clearly in iig. 2. Inwells and .cisterne where lead or wooden tubes are employed forelevating the water, I make `use of l a coupling,

H, (iig. 3,) for connecting either to the tube C of the filter.This'coupling is constructed as shown, and consists` of a thimb'le orcollar provided witha ledge or shoulder, o, at the centre, runningtransversely 'around the inner .surface so as to lessen the size of thebore or opening, while atV both ends of the thimble, above and belowthis shoulder is cut an internal thread, for screwing on the end of C,and the endof I the wooden tube vIP, (shown in.

red lines.)y If a lead tube, Q, is 'desired to beused instead of thewooden one, the coupling is slipped over the same, so 'that the Bange orcollar, s, at tube end of the tube will be below the shoulder, o. Thecoupling H is then screwed on the end of tube C, the end of ywhichpresses the Bange 8,'against the shoulder o, firmly securing the lformerin place. Aring of rubber or other suitable packing material may beinterposed between tl:\?\liangt...il and end of C, te insure the jointbeing water tight.

If desired. the cases F and Gr, either or both, may be made of crooks orcylinders of unglazed earthenware, when the perforations n n may bedispensed with, if preferred, as the earthenware is sufficiently porousto freely admit the rpercolation or passage of the water through it intothe filtering space, and from thence into the .reservoirI and tube C.When so constructed, the pores of the oppositepside's may be` closed.by'glazing the surfaces on alternate sides to produce the effectlobtained by the mode of perforating, where metal is used.' A singlecrock or case of earthenware may be employed, thereby dispensing withthe space and filtering material L, in which case it should be made ofgreater thickness; or the sides of the filter may be constructed `ofbricks laid up in mortar, through which the water will readily pass 'byfiltration, the brick or earthenware forming an excellent material formost eifectually straining and otherwise purifying the same.

Figure 3 isan enlarged sectional view of the cbupling H, for connectingeither lead or wooden pipe with The object of my invention is to enablea compact and'portable iilter' to'be constructed in connectioii wtih thesuction-pipe of .the pump so as to enable the complete filteringapparatus to be lowered 'into a well containling water by means of saidpipe, and removed therefrom for repairs, when required, in like manner,and thisM I accomplish bymaking the base plate E serve as a platform onwhich the sides of the filtering chamber are erected, whether of brick,earthen, or of loose porous material supported by outer and inner walls,and completing the wh'oleiwith the cover-plate D, which is screwed downso-as to press closely on the sides. By coupling the central tube C tothe pump-pipev B, the filter becomes attached to the pipe so as to behandled by i't. This obviates the-necessity of emptying a. well of waterin lorder to construct or insert the lter in it, and makes it entirelyunnecessary for workmen to descend into a well at all. What I claim anddesire to secure by Letters Patent, is` v A portable well andeistern-iilter composed of the sub-plate E, filtering cylinder F G',disc D, nut or fastening j, andnperforated central tube C, combined withand attached tothe pump-tube B, the whole constructed and arrangedsubstantially as and for the purposes set forth.` l

I alsoV claim the partially perforated sides F and G, when constructedas described, in combination with the porous packing lL, base-plates D,E, and tubes C and B, arranged and operating substantially in the mannerand for the purpose described. f
